Screen resolution and image quality
I am new to building apps from source code in Mac and to QT, so this may seem very basic. I have a MacBook Pro running OS X Mavericks with a retina screen (3360 x 2100). QtDesigner 4.8.6 and other apps I have built on Qt 4.8 (such as QGIS) have graphic objects with a very low resolution -- like older displays. I am wondering if this has anything to do with my configuration when I installed Qt Designer from source code? Perhaps a ./configure setting? Or is this another problem? What can I try?
I am particularly keen to improve the display quality of QGIS as this is a mapping app and I need to see my output nicely on screen.
Thank you to all this who can help.
What do you mean by low resolution? Do you mean the windows are smaller when the app is opened? Do you mean they appear fuzzy?
As far as I know there is nothing Qt does that has any affect on resolution. That is between your OS/vid card/monitor.
My guess on low resolution looking stuff is scaling from your monitor or video card. It makes things appear fuzzy and just generally crappy.
I'm running a 4k (3840x2160 res) monitor and all my Qt stuff is just as clean and crisp as any other application. If I turn on scaling of any sort then things get blurry/grainy.
